AUGUST E. ROEVER, OF BROOKLYN, NEW' YORK.

VACUUM ASH-SIETER.

Application filed May 27, 1920.

. fore war was declared by the United States against Germany, and who still expects to become such citizen of the United States,)

residing at Brooklyn, in tne county of Kings,

city and State of New York, have invented certain new and useful Improvements in Vacuum Ash-Sitters, of which the following is a specification.

This invention relates to ash separators or sifters particularly adapted for use with motor driven vacuum cleaner apparatus, the object of the invention being to provide an improved separator or sifter for the purpose specified, very simple in construction and operation and durable in use and which can be readily used with an ordinary household or portable motor driven vacuum cleaner by merely placing the same on top of the separator or sifter.

In the drawings accompanying and forming a part of this specification, Figure 1 is a side view partly in vertical section of this improved vacuum sifter or separator, the dotted lines illustrating a portable motor driven vacuum cleaner placed on top of the cover of the sifter; Fig. 2 is a plan view partly broken away; and Figs. 3 and 4 are detail views of part of the cover.

Similar characters of reference indicate corresponding parts in the several figures of the drawings.

In the preferred form thereof, this improved separator or sifter comprises preferably a metal box of a suitable size adapted to be set upon an ordinary metal ash can. This boX 2 is provided at one side with an inlet or nozzle 3 for the reception of a suitable conduit or hose leading to a suitable nozzle adapted to be used with ashes, such for instance as that shown and disclosed. in my contemporaneously pending application filed simultaneously herewith. This inlet 3 opens into one compartment as the bottom compartment 4 of the receptacle or box, this compartment being divided from an upper compartment 5 by a suitable screen or separating medium 21 preferably of cloth or fabric through which the air may percolate and by means of which the dust and dirt are prevented from passing from the cornpartment 4 into the vacuum cleaner. The

Specification of Letters Patent.

Serial No. 384,553.

bottom of the receptacle is provided with a depending chute 6 having a discharge outlet 6 of suitable size adapted to open into an ash can. The bottom of this outlet 6 is provided with a closure or cover 7 hinged to the outlet 6 and of substantially the same size as said outlet, and provided with a suitable means for opening and closing it, and which opens downward for the discharge of the dust and dirt.

In the present instance this ine-aus consists of a connecting rod or link S having its upper end connected to one arm as 9 of a rock shaft 10 suitably mounted in the side wall of the receptacle 2, and on its outer end provided with a suitable handle 11. The movement of the handle in one direction is limited by a pin 12 and b throwing the handle against this pin 12 see dotted line position Fig. l), the closure 7 is closed against the lower end of the outlet 6 and maintained in such closed position by reason of the fact that the connecting rod or link is thrown past its dead center position, and thus locks the door shut against premature opening.

The receptacle is provided with a suitable preferably removable cover v13 maintained air-tight by means of a suitable packing 14 either carried by the cover or by the top edge of the receptacle. This cover is provided with an elongated slot 15 faced or inclosed by a suitable packing of felt 16 and with a pair of handles 17.

It will be understood of course that the various details may be more or less changed without departing from the spirit or scope of the present improvement.

, In operation, the cover having been tightly fitted to the box and the box 2 placed on top of an ash can 2() in the manner shown in Fig. l, an ordinary portable electric vacuum cleaner 3() is placed on top of' the receptacle cover with the inlet 31 of the vacuum cleaner in juxtaposition to the slot or opening 15 of the cover, which is of substantially the same area as that of the cleaner. A suitable hose and nozzle are attached to the inlet 3 and the closure 7 closed whereupon on operating the motor driven cleaner suction will cause the particles of dirt and dust of the ashes to be drawn in through the nozzle 3 'into the receptacle 4 and the air purified and drawn through the screen 21. the slot 15 and into and through the motor-driven cleaner. In this manner the cleaner is maintained free from dirt and dust, which all settles and remains in the lower compartment 4 of the receptacle 2. When the same is filled or partially filled, the operator by manipulating the handle 11 opens the outlet 6 and permits the same to drop into the ash can.

Thus the present improvement provides a very effective and sanitary ash separator or sifter, simple in construction and eiiicient in use, and which as stated, can be used with an ordinary vacuum cleaner or portable motor driven vacuum cleaner, which may in practice be suitably clamped or secured to the cover or to the handles 17 thereof if preferred to maintain it in place.

I claim as my invention:
